SPECIFICATION forming part of Letters Patent No. 606,124, dated June 21, 1898.

'Application ined October 25, 1897.

To all wiz/0m it may concern:

Be it known that l, WARREN H. CRAIG, of' Lawrence, county of Essex, and State of Massachusetts, have invented an Improvement in Bicycle-Saddles, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

The present invention relates to a bicyclesaddie and is embodied in a saddle ofthat type now commonly known as the hygienic saddle,in which the weight of the rider is supported wholly above the, pommel 'or forward projection, which may be omitted, if desired, but is commonly used as alateral guide-,support for the rider and 'also as a meansv for obtaining a longer saddle-support, so as to obtain a sufficiently long and flexible spring.

The object of the present invention is to simplify the construction of a saddle of this class and to so construct the saddle that the seat or cushion portion is practically independent of the supporting portion to which it is secured, and which in turn is adapted to be secured to the seat-post of the bicycle. The supporting portion aforesaid is arranged to constitute a spring-support for the seat or cushion and is herein shown as having a transverse member extending crosswise and curved to form a substantially horizontal loop which constitutes the main seat-support, and a longitudinal member extending lengthwise of the saddle to aiford a support for the front portion of the seat, and, if necessary, a forward extension or guide portion corresponding to what is commonly known in bicycle-saddles as the pommel, the said forward extension being provided with a cushion, or not, as it may be desired. The said longitudinal member is also adapted to be secured to the seat-post. As herein shown, the supporting portion consists of a single integral piece of wire having at about the mid'- dle thereof a substantially straight portionL adapted to extend transversely across the saddle and underlie the seat portion thereof, the wire bein g bent around and curved around until it crosses said straight portion and thereby forms the loop aforesaid ateach end thereof, and then being curved downward and toward the front of the saddle, where tions or cushion-holders.

Serial No. 656,255. (No model.)

the ends are secured in a ,clamping-piece, which may also, as will be described, constitute the fastening device for the seat portion at the front end thereof and the means vfor connecting together two separate seat por- The said seat portion preferably consists of two such cushionholders, each containing a cushion and each being similar in shape to one side of the seat portion of an' ordinary saddle,so that together v theyform a seat having a longitudinal middle l space to afford ventilation. The said cushionholders,which may be of sheet metal dished or upset along the edge to form pockets for vthe cushions, are shown as secured at their forward ends to the support by means of bolts, the heads of which may also be within the material which forms the bottom of the cushion, so thatv theA cushions, cushion-holders, and support are all clamped together at this point by a single bolt. The main portions of said cushion-holders lie upon the transverse supporting-loops aforesaid, which are of suiiicient size to afford adequate supportfor said cushion-holders, the said parts being curved or shaped to conform to each other, while the holders are clamped or otherwise secured thereto in anysuitable or usual way.

The support for the saddle is herein shown as consisting of a single integral piece of sufficiently heavy wire, having a transverse por- IOO tion a extending across the saddle substantially at a right angle to the longitudinal median line thereof, the wire then being curved at a2 and the ends thereof being finally carried around to a position substantially parallel with the longitudinal median line of the saddle to aiford the main longitudinal portion of the spring-support, (indicated by the reference-letter a3.) As shown, each of the said curved portions lies in substantially the same plane as that of the transverse portion a and -crosses the same, thus forming a horizontal supporting-loop conforming approximately to the shape of the seat portion supported thereon and of such size as to constitute a firm support therefor. The ends of the said wire are shown as secured together by means of a clamp b, the said clamp having two longitudinal openings for the said ends and being split, as indicated at b2, so that the upper and lower walls of said bores can be drawn together upon the ends of the wire which forms the support by means of nuts h3, secured to bolts b4, to complete the supporting portion of the saddle. (See Fig. 7.) The seat portion of the saddle, which is adapted to be secured to and supported by said supporting portion, is shown as comprising the cushionholders c, containing the cushions d, which maybe of any suitable construction or material, the cushion-holders being secured at their forward ends to thc support, as by means of the clamping-bolts b4, and heilig supported at the rear of their forward points upon the transverse horizontal loops above described. Tohold the said cushion-holders in place, any suitable fastening devices may be employed, the said holders being herein shown as provided with bolts c2, extending downward through openings c3 in the bottoms of said holders and each having a clamp member c4, provided with a projection c5, adapted to engage the wire a, and a nut c6, which clamps the said transverse portion a of the wire between the bottom of the cushion-holder and the clamping-piece, as best shown in Fig. 6.

The specific shape and construction of the support a a2 a3 may obviously be `varied without departing from the invention, the form shown in Figs. l and 2 being especially desirable where a very springy and easy saddle is desired. In this instance the curve Co2, after the horizontal loop is formed, is carried downward and rearward, as shown at d20, and thence forward of the clamp b and curved, as shown at a3, to the rear, the ends of the longitudinal members d3 entering the openings in the said clamp b from the front thereof. In this way a flexible and easy spring is obtained, the effective length of the spring being very long, so that there is sufcient strength without excessive stiffness. There a more rigid saddle is desired, moreover, and one which will stand closer to the seat-post or frame of the machine, the curve a2 may be turned to the rear of the transverse portion a to form the loop, as shown in Figs. 4 and 5,

the longitudinal portions a3 extending forward directly from the general curve a2, being bent downward, as shown in Fig. 4:, only far enough to clear the straight transverse portion a and then bein g bent upward and entering the clamp b from the rear. rlhe rods may, if desired, terminate within the said clamp, or they may, as shown, extend forward through the same to form a forward pommel or guide projection, the said pommel being shown in Fig. 4 as provided with a cushion at, adapted to be secured to the projecting ends of longitudinal members CL3. In Fig. l1 the transverse portion a is shown as curved, so that the width of the seat may be adjusted by loosening the nuts c6 and swinging the said seat portions on the bolts by which they are connected at their forward ends as pivots.

In any form it will be seen that the seat proper is mainly supported on two substantially horizontal spring-loops integral with the longitudinal member of the support, thus affording a substantially universal spring adapted to yield in any direction with a movement of the riders body, but at the same time forming a broad support for each cushion, so that the same cannot materially tip sidewisc.

As shown in Fig; 3, the heads of the bolts b4 are preferably within the cushion d, so as to overlie the material which constitutes the lower surface of the cushion-pad, so that the cushion, cushion-holder, and support are all fastened together at this point by means of the said bolt.

To secure the pad of the cushion to the cushion-holder, the said pad is provided with a pin or fastening device (Z2, having a head d, adapted to rest upon the surface of the cushion, while the said pin (Z2 extends downward through the same and through an opening in the bottom of the cushion-holder c, where it is held by a fastening device d4, which extends through a transverse openi ng in the said pin, so as to engage the bottom of the cushion-holder. By this device the cushion is firmly held in position in the holder, while an indentation is made at about the middle of the cushion, so that the surface of the saddle conforms better to the person. The cushion and holder are then substantially one part, the fastening devices having been previously inserted, and'said seat portion, as it maybe called, is ready to be secured to the support.

It will be seen that the fastening device b constitutes a retaining projection or shoulder which prevents the upward movement of the pin d2, but does not prevent the downward movement thereof, so that while the cushion is `securely held in the cushion-holder it is `free to 7ield under the riders weight without any liability of the head o f the pin comingin contact with the riders person.

As shown in Fig. 3, the cushion may be provided with a plate (l5, of any suitable material, to strengthen the same and afford a rest for the head of the bolt b4, such plate, however, forming no essential part of the IOO IIO

structure, since the cushion-holder itself may obviously form the bottom of the pocket for the cushioning material, the up er or flexible portion being firmly secured t ereto bythe fastening device d2.

lVhile the cushioning material used for the seat portion of the saddle may be varied without departing from the invention,` it is practicable and in some cases desirable to use a pneumatic cushion, and apneumatic cushion especially adapted for this purpose is herein shown, the construction illustrated forming a' feature of the invention.

Referringto Fig. 8, the flexible covering` portions for the seat are shown as connected together by a tube d6, and the pneumatic cushion used in this instance consists of two separate chambers e and e2, each shaped to conform to one side of the saddle and connected together by a tube e3' to afford a restricted air-passage from one chamber to the other. The said cushions are adapted, as best shown in Fig. 10,-to be inserted between the cushion-holder c and the flexible cover, there being preferably inserted a layer 020 of felt or other suitable material between the bottom of the chamber and the surface of the cushion-holder c.

In order that the cushions may be properly secured to the holders, each chamber has an open tubular passage extending substantially through the middle of the same and the pin d2 is passed through the flexible cover substantially as herein described and through the said passage from one side of the airchamber to the other and then through the cushion-holder c, where it is secured substantially as shown and described in connection with the cushion shown in Fig. 3. By this construction the whole seat portion can be inflated at once and the pressure equalized in both chambers, while means are afforded for properly securing the cushions to the holdersV and for properly shaping the upper surface of the seat.

The saddle as a whole is adapted to be secured to the seat-post A of the bicycle by any suitable or usual clip B, the clip herein shown being substantially like that shown and described by me in a prior application filed July 24:, 1897, Serial No. 645,793. Y

It is not intended to limit the invention to the specific construction herein shown and described, since modifications may be made without departing from the invention.
